ARTHUR ROSSI, or SAN FRANCISCO,

COMBINED GRAPE CRUSI-IER,

To all whom it'mag concern:

Be it known that I, ARTHUR ROSSI, a su ject of the King of Italy, residing in th city and county of San Francisco, State of California, have invented new and useful In'iprovements in a Combined Grape Crusher, Stemmer, and Must- Pump, of which the following is a specification.

This invention relates to combined grape crushing, stem removing and must pumping machines for the use in the process of wine makingfroni grapes, and has for its object the production of mechanism that will complete in one continuous operation the several performances required in said Another object is to obviatethe defect, now inetwith machinesof this naturego? the frequent (Digging of the suction pipe of' the must pump by pomace, andi'in this way eliminate the necessity of frequent stopping of the machine, the removal of all the liquid contents from the must pan, and the cleaning of .the suction pipe of the must pump.

To these ends and objects chiefly my invention embraces a pair of crushing rollers elevator for the delivery of" clusters of grapes into said hopper, a feed controller to regulate the discharge from the hopper into the crushing rollers, means for detaching ter from the machine, and collecting the former in a must pan, and novel devices fdr keeping the must agitated while in the n.

The invention embraces further a pump to remove the must fromthe'pan, and deliver it to a higher elevation into the must tanks. a

The invention further embraces a novelconstruction and arrangement .of parts and mechanism, producing a continuously operating machine, that will not readily clog, all as hereinafter described and set forth. The following description explains at length the nature of my said invention, and

carry out the same in the production of an improved machine for thepurpose named, reference being had to the drawings that ac company and form part thereof.

Figure l is an end elevation of the machine. Fig. 2 is a cross section taken through a z, of Fig. 3. Fig. 3 is a front elevation- F ig.v 4 is a longitudinal section Specification of Letters Patent. Application filed July 25,1913.

For convenience of describing the principal parts of this machine they are desig nated by letters. T

A is a cast iron base provided with wheels or rollers a. B and-B are standards fas tened to said base and are tied together by the, channels C-C B is a standard fastened on top of the channels. i I

is a crushing roller provided with journalscZ-d, working in the boxes d, and d on'the standards B and B anddriven by the gear (Z g E is a'crushing roller that works cooperatively with the roller D. with the journals .6, and 6,, working in-the bearings 0 and 0 held yieldingly in posik'ti'onjn' the standards B and B by means of th'e springs 0 and. 5. The. two crushing vrollers are geared together at their rear ends by the gears (Z and, 6,.

.F is a feed hopper set above the crushing rollers adapted toreceive clusters of grapes to beacted on in the machine. Inside the hopper F, somewhat above the crushing 'ler G, which consists of the shaft 9 provided with a number of prongs g, arrangedin rows radiating from the shaft outwardly. The shaft g works in'the boxes g, and 9 of thegears (Z and 9,. I --H1s a feed elevator for the delivery of grapes to the feed hopper. (Shown in the It is suspended/from the arms H and H, of the standards B and B and is driven by a link belt h conneeting the sprocket wheel (Z, set on shaft (Z with a similar sprocket wheel 71., set on the elevator shaft 7a,.

The stem removing mechanism consists of the shaft j, one end of which is mounted in the box y',, set in'the standard B, and the other in a bracket bearing j fastened to the channels (l -C, at the discharge end of the machine. It carries a number of arms .71; extending radially and arranged in a double helix. Beneath the shaft there is a perforated casing K semicircular in cross section. It is closed at the head end bythe solid part of the standard B, while the other end, being left open passes through a circular opening in the standard B, and terminates just a little beyond that standard. L is a cover of solid sheet metal also semiciron line blb of Fig. l.

gether with the casing K a complete cylindrical casing. The cover Lhas at its head pr o'vided with a conveyer blade m The shaft rests in the bearings m m on the standards B and B and carries a spur gear m N is a pan or casing within which the must is collected. The bottom of the casing is made to follow the circle of the agitator,

then the two ends extend upward and terminote at the channels C-C At the discharge end of the pan N there is a discharge pipe 72, having ajflange a suited to fit a similar flange a of the suction pipe P of the must pump P.

P andP are standards fastened to the base A, which carry the pump cylinders and P The pump body P is fastened to the base A It has a suction pipe P and a discharge pipe P I Q and Q are cranks set on the ends of the crank shaft Q to operate the pistons in the cylinders P and P R is a counter shaft which rests with one end in the box on the standard B and with the other in the box r 'on the standardP its object is to transmit the motion from the shaft j-to the crank shaft Q of the pump by means of the gears j 1;, r and Q The following 18 the operation of the machine: The shaft is driyen either by a belt and pulley or by a motor (not shown in the drawings), ,.@his-'rotary motion is trans-' mitted 'to' the crushing rollers D- and E through the gears :2 dad and 6 The feed controller shaft 9 is driven by the roller D through the gears (Z and 9 While the elevator shaft in is run from the same roller D by the link belt 71 and sprocket wheels (Z and h The agitator shaft shaft m is operated from the shaft y" by means of the gears j 1- and m while the pump shaft derives its motion from the sameshaftjthroughithe gears j r. counter shaft Rand gears T and Q All tne shafts have their motions in the directionsshown in the drawings by the arrows. H The material to be handled by the machine, consisting of clusters of grapes,

is fed by hand upon the belt of the elevator- 11 and is discharged by the "atter into the hopper F above the feed controller G. From here it is fed at a steady rate between the of the grapes and pressing out the must, dis

charge the material through the funnel Z,"

letting it fall into the casing K, where the juice of the grapes drains down through the roe rei'r perforated casing K into the pair 25, whilethe stems and the shells are caught bythe prongs 7' of the stem removingmechanism skins of the grapes get detached from the stems, while moving along the rough per fo'rated surface of the casing K and are discharged through the perforations into the pan N while the stems are gradually carried toward the discharge end of the machine by the prongs 7' which being spaced in a helix have to a great extent, the effect of a screw; The juice and shells of the grapes after passing the perforated casing K collect in the pan K. The must collected in the pan Nubile kept. agitated by the motion of the helical blade m is driven toward the discharge pipe at, where it arrives in a state of uniform consistency, being fluid enough to be drawn in by suction into the pump cylinders P and P and discharged through the pipe P into the -must tanksat a considerable height above.

The crushing rollers D and E may be on'ritted in some machines built under this design. In such case the clusters of grapes delivered into the hopper F are directly fed by ,thc'controller G into the casing K and L through the funnel Z, where they are caught by the prongs 7' and subjected to a rapid peripheral speed.

"The shells or skins of the grapes, due to impact against thestationary walls of the inclosing casing, become ruptured, detached from he stems and discharged through the perforated casing K into the must pan N.

It is evident that by the arrangement of the mechanism as illustrated in the drawings and described above, the performance of the machine is continuous and the tendency'of cloggingof the suction pipe of the must pump is entirely eliminated by keeping the pomace of uniform consistency before it becomes subject to the action of the pump in the suction pipe. p What I claim and desire to secure by Letters Patent is:
